青霉素-鏈霉素-兩性霉素B溶液(三抗),100×
貨號:PB180121
價格:¥180
- 100mL
產(chǎn)品概述
青霉素-鏈霉素-兩性霉素B(Penicillin-Streptomycin-Amphotericin B Solution)混合液是體外培養(yǎng)中常用的抗生素溶液,也叫做“三抗”。其中,青霉素(Penicillin)能夠干擾細(xì)菌細(xì)胞壁的合成,對革蘭陽性菌有效;鏈霉素(Streptomycin)能夠與細(xì)菌核糖體30S亞單位結(jié)合,抑制細(xì)菌蛋白質(zhì)的合成,對革蘭氏陰性菌和革蘭氏陽性菌均有效,尤其是革蘭氏陰性菌;兩性霉素B(Amphotericin B)能與真菌細(xì)胞膜上的麥角甾醇結(jié)合,導(dǎo)致細(xì)胞膜受損,通透性提高,細(xì)胞內(nèi)物質(zhì)外漏,破壞正常代謝而起抑菌作用,但對細(xì)菌無效。青霉素-鏈霉素-兩性霉素B聯(lián)合使用可以預(yù)防絕大部分的細(xì)菌和真菌污染。
